How can I tell the orientation of my proof for my 2-sided job; how it "backs up"?

Print jobs we produce will ALWAYS back up in the same manner. Basically, the top edge of the PDF PAGE on your screen will back up the top edge of the next PDF PAGE. Please do not confuse this with the orientation of the ART. Another way to think about it, is the filename identifiers will always back each other, on the same edge. If you have ANY unresolved questions about how your proof will back up, please DO NOT approve your proof and get your question answered first. You will be held responsible for checking the orientation of your proof from us, with your proof approval.
